Description

Semiconductor ultraviolet and ultrasonic combined water treatment device

Technical field

The utility model relates to a kind of semiconductor ultraviolet and ultrasonic combined water treatment device, belongs to technical field of sewage treatment equipment, mainly to carry out disinfection organism in sterilization and the degradation water of sewage.

Background technology

Because developing rapidly of industry, the kind of pollutent increases year by year, and traditional water treatment method has seemed and no longer adapted to.Open wastewater disinfection treatment facility adopts the disinfection by ultraviolet light technology, utilizes ultraviolet ray that efficient, wide spectrum that pathogenic microorganisms such as bacterium, virus have are killed ability, reaches water and purifies and the disinfectant purpose.

In run duration; the ultraviolet lamp that Ultraviolet Disinfection adopted is along with the pollutant sediment of protective quartz tube-surface causes light intensity weakening and reduces germ-killing efficiency gradually; therefore must when the design sterilisation system, all stay bigger surplus; make the light intensity of fluorescent tube drop to 60% of rated value, total system is still moved.One of core of UV disinfection system is exactly a ultraviolet lamp tube, and fluorescent tube adopts low-pressure high-strength ultraviolet mercury lamp pipe, and the peak power of single fluorescent tube can reach more than the 400W, could guarantee that ultraviolet output reaches more than 40%.Fluorescent tube expected service life is 8,000～1,2000 hours, is subjected to the influence of factors such as on-the-spot working conditions, fluorescent tube switch number of times, effluent quality and fluorescent tube cleaning frequency its work-ing life.Its shortcoming is: in the open wastewater disinfection water treating equipment, ultraviolet lamp tube is multi-sealed in the quartz glass sleeve of high-transmission rate, and at back panel wiring, outer wall uses water-proof material, can not guarantee for a long time that ultraviolet lamp tube is in state of insulation, and have a series of problems such as device complexity, power cost height, fluorescent tube are changed frequently, processing costs height.

Summary of the invention

The utility model provides a kind of semiconductor ultraviolet and ultrasonic combined water treatment device, utilizing semiconductor ultraviolet and ultrasonic combined effect that water body is carried out disinfection sterilizes and degradation of organic substances, and in treating processes, semiconductor ultraviolet and ultrasonic combined effect are unlikely to the passing of the time that is subjected to and make the too fast decline of efficient.

For achieving the above object, the technical solution adopted in the utility model is: a kind of semiconductor ultraviolet and ultrasonic combined water treatment device, form by tank, ultrasonic wave vibration plate and LED luminescence-utraviolet plate;

Described tank open at both ends, its front end is uncovered to be flow inlet, and rear end opening is a water export, and tank is connected and composed successively by close up section, venturi section and flared section from front to back;

The described bottom land that closes up section is a horizontal plane, and the spacing between two cell walls is dwindled from front to back gradually, and the section horizontal direction cross section of closing up is trapezoidal; The bottom land of described venturi section is the plane of declivity from front to back, and the horizontal direction cross section of venturi section is a rectangle; The bottom land of described flared section is to go up oblique plane from front to back, and the spacing between two cell walls enlarges from front to back gradually, and the horizontal direction cross section of flared section is trapezoidal;

Described ultrasonic wave vibration plate is made of several ultrasonic transducers that an oscillating plate and being used to drives this vibration plate vibrates; Described LED luminescence-utraviolet plate constitutes by establishing several ultraviolet diodes on the substrate; In described ultrasonic wave vibration plate and the LED luminescence-utraviolet plate, one are positioned on the bottom land or cell wall of the described section that closes up, and another person is positioned on the bottom land or cell wall of described venturi section.

Related content in the technique scheme is explained as follows:

In the such scheme, described tank is the Bashel water measuring tank.

The utility model principle of work is:

(1) form the unhurried current effect according to the Bashel groove:

Three sections of closing ins, venturi, enlarging are arranged in the design of Bashel groove; the current that can reach wide progressively draw the unhurried current effect in; when when the section that closes up is installed LED luminescence-utraviolet plate; can increase time of ultraviolet irradiation; progressively carry out the water conditioning of ultraviolet effect; both sides, the narrow and small passageway adjustable ultrasonic wave vibration plate of installation power by venturi carries out water conditioning then, gets rid of by enlarging at last.It is less that the Bashel water measuring tank also has head loss, is difficult for the characteristics of alluvial.

(2) form cavitation effect according to ultrasonic wave:

With multiaspect to the ultrasonic wave vibration plate, ultrasonic wave produces the particle acceleration that surpasses several ten thousand times of universal gravity constant in water, form cavitation effect, produces about 4000K, 100MPa moment high temperature and high pressure environment, the speed generation with about 110m/s simultaneously has intensive shockwave and jet etc.Water molecules reaches supercritical state at focus, and resolves into free radical, super oxygen base etc., and organism on focus reactions such as chemical bond rupture, water burning, high temperature splitting decomposition, supercritical water oxidation, free-radical oxidn takes place, and reaches the organic matter degradation effect.

(3) according to the disinfection of ultraviolet waves:

Ultraviolet ray can penetrate microbial cell film and nucleus, destroys the molecular linkage of nucleic acid (DNA or RNA), makes it lose replication or loses activity, and changes the biological activity of DNA, makes not reproducible of microorganism.Thereby inhibition, eliminating bacteria virus under the situation of not using any chemicals, degradation of organic substances etc.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, because the utility model utilization Bashel groove principle of design, in closing in, venturi, the flared fluvial processes, that design LED luminescence-utraviolet plate carries out is antibacterial, sterilization, organic matter degradation, the ultrasonic wave of the particular frequencies that produces by the ultrasonic wave vibration plate causes the cavitation effect of water quality then, produce the effective degradation of organic substances of free radical, operation of equipment is simple, and antibacterial sterilization speed is fast, organic matter degradation is obvious, the automatic controlling level height.

2, since the utility model ultrasonic wave vibration plate by an oscillating plate and several ultrasonic transducers that are used to drive this vibration plate vibrates constitute, when the frequency of single ultrasonic transducer is identical with power, the power of ultrasonic wave vibration plate is more powerful, and that therefore handles is wider.
